pubescent; secondly, with a stem 3 feet high; thirdly, 
with the leaves occasionally subserrulate ; and, fourthly, as" 
having middle-sized flowers and entire petals. Now in 
@. pallida, the leaves and calyx are perfectly destitute of all 
kind of pubescence, both in the cultivated and spontaneous 
specimens, the stem never exceeds a foot or foot and half 
in height, the leaves are never subserrulate, although they 
are often dentate or slightly pinnatifid, the flowers can 
scarcely be described as middle-sized, and the petals are 
the reverse of entire. 
From 4. pinnatifida of the same author, it is obviously 
distinguished by the total absence of pubescence; and the 
same peculiarity divides it from @. speciosa, to which it has 
otherwise a strongly marked affinity, especially in the colour 
and appearance of its flowers, in its general habit, and 
creeping roots,—a character far from common in the genus. 
From the beautiful @2. roseo-alba of Reichenbach, it is 
distinguished by the length of the tube of the calyx. 
Flowers from June to September. It is increased 
readily by its creeping roots, and also by. seeds, which 
are produced in small quantities. It flourishes more in 
peat than in a loamy soil. ae 
Stems erect or decumbent, a foot or foot and half high, 
branched, pallid, angular, smooth. eaves linear, acumi- 
nate, entire or dentate, smooth, rarely pinnatifid. Iowers 
axillary, erect, longer than the leaves, at first white, after- 
wards pink, emitting a delicious fragrance at night. Ovarium 
linear, with four furrows, incrassated at the base, smooth. 
Tube of the calyx filiform, the length of the ovarium. Calyx 
membranous, quite smooth, its limb not more than half 
the length of the tube. Petals retuse, denticulate, much 
larger than the calyx. Stamens shorter than the petals. 
Anthers long, linear, versatile, yellow. Capsules linear, 
falcate, twisted, between fibrous and woody, inseparable 
from the stem unless torn off by force. Seeds linear, cuneate, 
pale brown, acute at the base, with a smooth surface.
